28 Claims. l

This invention relates to an agricultural implement attachment for vehicles and is primarily concerned with the provision of improved supporting or mounting structure for mounting a corn harvester or the like on a tractor or similar vehicle.

The invention contemplates and has for its principal object the provision of a row-crop unit that may be conveniently supported on and carried by a mobile frame. The design of such unit is developed around a main support on which the various components of the harvester are mounted and within which a major portion of the drive mechanism is contained. The basic design constitutes a radical departure from constructions heretofore known, of which the conventional oneor two-rowvcorn picker may be considered typical.

In such prior constructions, the usual picker was primarily designed for attachment to a parin the design of such prior pickers lay in the .structural characteristics thatrinvolve the provision of relatively complicated framework with which the various components of the picker were inextricably tied together, alloof which complicated the design in general to such extent that maximum efficiency could be obtained only in use of the picker with the tractor for which it was fundamentally designed, and even then that efficiency was considerably below what could be expected. v l

According to the present invention, the main support or backbone of the row unit comprises a casing which contains the several parts of the driving mechanism. This driving mechanism includes a plurality of output shafts which are ac cessible through walls .of the casing. The exterior of the casing is provided in such manner that it has a plurality of attaching or mounting surfaces on which the various componentswof the implement may be mounted. In the case of the adaptation of the principles of the invention to a corn picker, for example, the snapping and gathering unit may be mounted on one face of the casing, while the husking or crop-receiving means may be mounted on the opposite face. The rotatable components of these two units are 4then connectible to the output elements of the driving mechanism. The entire arrangement is such that the units maybe readily assembled to or separated from the supporting casing. lIn

2 v another aspect of the invention, the Supporting casing is mounted on the vehicle-which may be a tractor or a drawn mobile frame-by means of a torque arm which is preferably hollow `and whichl contains a power input shaft connected to an input element for the driving mechanism within theV supporting casing. g n

In addition to the attainment of `objects herent in the design characteristics 1 outlined above, the invention contemplates the provision of an improved and inexpensive agricultural img plement, one that may be readilymounted on any type of tractor or other vehicle, andone that may be readily assembled fand dismantled, the arrangement of the various components being such that one or the other may be separated without disturbing or materially affecting vother components. l Y

The foregoing and other important objectsand desirable features inherent in any encompassed by the invention will become apparent to 'those versed in the art as the disclosure of a preferred embodiment of the invention ismade in detail in the following specification and accompanying sheets of drawings in which: l' p l Figure 1 is a side elevational view of a tractormounted corn picker, the near rear wheelA of th tractor having been omitted to expose the structure therebehind;` V Figure 2 isa fragmentary plan View ofthe structure shown in Figure 1, a portionl of the styling or-shielding being removed substantially along the line 2-2 of Figure l; ,p Figure 3 is a side elevational view showing the picker'in elevated position with respect to the tractor; l Y I Figure 4 is an exploded view showing therelationship' of the various parts prior to -assembly or following disassembly thereof; Y i Figure 5 is a longitudinal sectional view taken substantially along the lline 5-5 of Figure `2;

The vehicle-mounted corn rpicker chosenlfor thfpurpos's of illustration has' several compo- 'nents wlil'ch, fundamentally, are somewhat :cenvtlrlal, and 'which 'will ne readily recognized. For the purposes of facilitating 'a quick understanding of the over-all disclosure, lthe picker iy be referred to generally as being of the 'self-propelled type comprising alvenlclc vanc a corn picker which in ludes-'one ormore lon- 'gitudina'lly' extending row units, Ieach comprising' snapping and gathering mechanism S, husking mechanism H, a first elevator F for moving snapped corn from the snapping s unit to4 the husking unit, and a wagon elevator W lntouvvhich the husliend ears are discharged by the huskmg unit.

The rear nlzf the bo'dy'lis provided with 'lateral'- ly outwardly projecting carrying structure, `here in -thefrlri of 'a tril'svers'erear'axle housing-22. nly oneof "such vhousings is illustrated 1n ithe drawings; althou'ghfit will be understoodthat a similar housing projects from the opposite side of the tractor; *Each housing carries a laterally outwardlyextending axle, only thatgfor the lefthand housing 22 beingindicated at 23 A(Figures s. lift structure contained within a housing 29 v,and includes a laterally extending rockshaft 3'0 to which isrigidly xed an adjusting arm 3l (Figure l). The particular type of power lift mechreferred to is not important in so far as Athe-present invention is concerned and that illustrated could be replaced by any other suitable type.

The tractor is, of course, provided with the usual sourceY of power, such as an linternal coinbustion engine (not shown) from `which power is derived. for driving .a rotatable element in the form of a power take-01T shaft 32 (Figure l).

yAs will be apparent-fromthe description toi-follow, the row-crop .unit provided according to the present invention may be mounted on a vehicle of'a type-other than that illustrated and-'such unit may-bereadil-y adapted to any suitable mobile frame, in which event the .power source and power lift mechanism will, obviously, 4be different from that illustrated. However, these details are relatively unimporant.

Main supporting structure (reference numerals `3355a) Th Suppltlllg -trl'ltl'li :i'th' lsW finit that lCludeS vth ggthrilg' v-lfld 'll'tfllig 'llhliislh yS and the 'lukI'lg llt lI-I ('O'IIJIQS'ESl e'SSelll/lly two vnia'in parts.- The firsto'f these in the Lio'r'n'l of a 'Support or torque ar'm '33 (Figures l, 4, 'T0 vand l2). This torque fa'rrn 'is of elongated tue bular construction 'and is positionable length*- wise alongside the tractor body' 2l), with Aits rear 'end proximate Yto the vleft-hand portion of fthe carrying structure or ali-le housing' A2'2. 'The rear end of the 4toiquearrh Yi's adapted to be carried py the housing structure and the lliie'airis 'provided for that purpose comprises a bracket 34, which is rigidly mounted on 'the axle housing 22, anda Vtransverse pivot pin 35 by means of which the 'torque arm t3 is connected to "the bracket 34 for vertical movement in a longitudinally extending plane. The forward di' front en'd of ythe torque arm '3'3 is flanged 'at 3S (Figures 10, 'i1 and 12) to :provideu a 4mounting portion for securing of 'the torque arm rigidly and removably to a second basic support element in the form of' a casing or housing 31. AS best shown in Figures 8 ahd'9, the casing 31Mis formedA of two complementary halves `3a and 39, `which are respectively the front and `rear halves of the casing. 4These halves,fwhen assembled, 'are vrigidly'held together by a pluralityof bolts, lthe halves being respectively provided with a plurality of ybolt 4holes lll) and 4l. Since certain of the 'bolts that secure 'the two casing parts together are utilized "for otherv purposes, detailed reference thereto will be deferred.

Ifn Ythe interests of vbrevity and clarity, `the casing 3l' will'be considered as an integral unit prising the spring 52.

.and no further referencerwill be made to the parts 38 and 39 except in specific instances.

The casing 31 is provided with a rear wall 42 which provides a transverse, generally upright mounting face of substantially greater area than the mounting portion provided by the flange 36 on the torque arm 33. The ange 35 is rigidly secured to this rear wall 42 by any suitable means,.such as a plurality of bolts 43 (Figure 11).

As previously stated, the torque arm 33 is of relatively rigid tubular construction and the face provided by the flange 3B is of substantial area. Likewise, the transverse pivot pin and transverse extent of the bracket 34 are substantial. The torque arm 33 thus becomes a relatively rigid thrust and torque member for mounting the casing 31 on the tractor. Any thrust imparted to the casing 31 is, of course, taken by the arm 33 and transmitted to the tractor rear axle housing 22. Similarly, any twisting strains developed in the row unit are taken by the torque arm 33.

In order that the supporting structure comprising the arm 33 and casing 31 may be stabilized or guided vertically, stabilizing or guide means is provided. This means is best illustrated in Figures 2 and 11 and preferably comprises a bracket 44 having a bifurcated lower portion 45 which carries a roller 46. The bracket 44 is secured to the inside of an offset mounting portion 41 onthe casing 31 (Figure 11). It will be noted that the portion 41 is offset laterally and vertically with respect to the major portion of the casing. The purpose of this arrangement will be brought out in greater detail below.

The stabilizing means further includes a bracketor bearing 48 carried by the tractor body 20 (Figure 2). This bearing or bracket journals a transversely extending rockshaft 49 to the outer end of which is fixed a downwardly and forwardly extending lever arm (Figures 1 and 1l). This arm engages the roller 46 from below and is further received between the parts of the bifurcated portion 45.

The rockshaft 49 extends, of course, across the tractor body 20 and is provided intermediate its ends with at least one downwardly extending,

rigidly attached lever arm 5 I. Counterbalancing means in the form of a relatively strong tension spring 52 is connected at one end to the arm 5l and is anchored at 53 at its other end to a portion of the tractor body 2U.

It will thus be seen that the main support comprising the parts 33 and 31, although pivoted on the tractor at 35 for vertical movement relative to the tractor, is stabilized by the means 44, 50 and is counterbalanced by the means com- It will be appreciated, of course, that the supporting structure carries considerable weight in the form of the snapping and gathering mechanism S and husking unit H, the details of which will be described 'subsequently.

For the purposes of facilitating the further description of the casing 31 in connection with the manner in which it supports the harvesting componentafurther reference will be made to the particular structure of the casing. As previously stated, the casing includes the rear wall 42 which provides a rear mounting face. Similarly, the casing includes a transverse, generally upright forward wall 54. The casing further includes an upper transverse wall which provides a generally at, rearwardly and upwardly incliningfsurface (that is, when the casing 31 is disposed ask shown in Figures 1 and 3 for example). The surface of this wall 55 is substantially below the level of an upper Wall 55a comprising part of the offset casing portion 41 (Figure 11). Likewise, the top wall 55 is laterally outwardly offset with respect to the casing portion 41. It Will be-noted in Figure 11 that the connection of the torque arm 33 at 36, 43 to the rear wall 42 of the'casing 31 is below the level of the upper or top wall 55.

Power adjustment of the mounting structure (reference numerals 56-61) Inasmuch as the mounting structure is pivotally carried on the tractor by means of the bracket 34 and pivot pin 35, it may be adjusted vertically, and for this purpose appropriate connections are made with the power lift arm 3|. A longitudinally extending lifting link 56 has an integral rear portion 51 curved `below the left-hand rear axle housing 22 and pivotallyconnected at 53 to the arm 3|. The link 56 extends forwardly to a .pivotal connection 53 with an arm 6U fixed to and vextending upwardly from the outer end of the rockshaft 49.

It will thus be seen that rocking of the rockshaft 36 in a counterclockwise direction, as viewed in Figure 1, willresult in rearward swinging of the lift arm 3l. the lifting link 56 rearwardly and will rock the rockshaft 49 in a clockwise direction, following which the arm 5U will engage the roller 46 and will pivot the mounting structure upwardly about the transverse pivot35. -The energy stored in the spring 52 acts in the s-ame rdirection and thus the spring will assist lifting the row unit. Since the connection between the roller 46 and the arm 53 is not positive-that is, the roller is not confined to movement with the arm 50- the row unit may float upwardly. However, because of the action of the spring 52, the arm 56 will tend to follow the roller upwardly during floating movement of the row unit. For Vthis purpose, the forward end of the lifting link 56 is slotted at 6l so that the spring will serve to counterbalance the row unit without `exerting force through the link 56 against the lift arm 3|.

Huslcing unit (reference numerals 62-99) The husking unit, hereinbefore designated generally by the letter H, comprises an elongated unit preferably made up of sheet metal sections and is generally U-shaped in cross section, as best seen in Figure 11. This unit has a front wall 62 (Figurel) which provides a mounting portion for carrying the unit on the casing 31. The wall 62 is provided with a plu'- rality of bolt openings 63 which are alined with certain of the bolt openings 40 and 4| inthe casing 31. The husking unit vwall 621s thus secured to the rear wall 42 of the casing 31 by a ,plurality of bolts 64 (Figure 11). The plate or wall 62' overlaps that portion of the casing wall 42 to which the front flange 36 0f the torque arm 33 is secured, and the bolts 43 which secure thel flange 36 t0 the casing 31 `pass throughbolt holes 65 in the wall 62 (Figure 13)., and the husking unit extends rearwardly as a cantilever.

The sheet metal structure of the husking unit provides an inner longitudinal, substantially upright wall vor sheet 66 which is curved outwardly and upwardly along its lower marginal edge to provide a trough 61. The outer wall of the husking unit is designated at 68 and comprises a longitudinally extending removable section which This in turn will move y .acetate 11 extendsv'downwardly' to Kadioin the trough 61;,...as att 9i.- A longitudinal 'partitionTM5,v which iszpreerably arcuate lin cross-section,I :extends length-- wise' "offy the 'hashing unit and `is spaced. fslightly above the trough Vii l@ #to-provide a second trough :l l.

"Since this space is separated from the trough 61 :by the rearward extension of vthe .partitiona'llL the husks are :discharged laterally, `as will be apparent Yfrom an examination of Figure 1.

The Vpartition .lo is perforated so that shelled com, reaching the `husk trough 'H along .with huskstmay pass adownwardly intox-the .lower trough Gl. This trough is thus a shelled-corn trough, and, for the purposeofzmoving the shelled corn rearwardly, 'thisftrough :carries a longitudinally extending.deviceA in the'forrn of an auger-94. `The auger 94 isrconsiderably-smaller than the husk auger Q l, but is suhstantiallyflonger than thehusk auger.

Q, 'Swapping unit (reference numerals 10D-138) The snapping unit S comprises an inner subassembly and an outer sub-assembly |01.

The'inner sub-assembly includes a longitudinally extending supporting member or frame element |02 which may be of any suitable construction. As shown in Figure 15, it is a fabricated ,element of tubular design having at its rear end a pair of flanges 103.

iianges |03, a plurality of bolts |04 which passv through the casing 31. The inner pair of these bolts serves also to mount the stabilizer bracket .44 on vthe casing (Figure l1). The sub-assembly |00'is thus rigidly and removably carried by the casing 31 and extends longitudinally forwardly therefrom to provide one of the components o the gathering and snapping unit.' The outer subassembly |01 includes a longitudinal frame or supporting member |05 which is, like the member |02, preferably of tubular construction. The member 105 has a rear ange or face |06 which provides a mounting portion for securing of theouter sub-assembly asl a cantilever. 4to the front wall 54 of the casing 31.I The means for accomplishing the securing of the subassembly |01 to the casing 31 includes a plurality of bolts |01 which pass rearwardly through the casing 31 and also through certain of the openings 63 in the plate 62. The inner pair of bolts 101 passthrough openings |08 in the plate 52 (Figure 13). The rigid and removable mounting of the sub-assembly |01 disposes the frame member |05 in longitudinal 'parallelism with the frame member |02 of the sub-assembly |00. As part of the sub-assembly 10|, there is provided a longitudinally extending snapping'roll |03,-the lforward end of which is journaled on the sub-assembly frame member 105 by the means shown in Figure '1. `The member 105 has an upper horizontal plate portion 1| 0 which isA provided adjacent its inner longitudinal edge with a pair of upstanding brackets I. These brackets carry rigidly a transversely extending sleeve 12 within which is carried a snapping roll supporting member 1|3. The inner end of the member ||3 is provided with an intersecting vertical portion f1 14 which receives a vertical pin 115 for mounting a yoke or bearing ||6 which -in turn carries the snapping roll |09.

That end of the member 13 adjacent the snapping roll |09 is enlarged at |11 to provide a guide which slidably carries the member axially of the sleeve 1|2. The outer end oi the sleeve |12 has rigidly secured thereto an apertured cap |18 .which is internally threaded to receive a sleeve extension 10. `The outer end of the member ||3, being in the form of a rod, is slidably received in the sleeve |19 and has itsextreme outer end'threaded at |20 to receive an adjusting nut 121. A compression spring |22 functions between the enlarged portion I 11 and the shoulder provided by the inner end of the sleeve extenvsion |19 and operates to hold the snapping roll |09 inwardly to the limited extent dened by the adjustment o f the nut 12|. The entire assembly may yield outwardly relative to the sleeve |12 and the sleeve extension |19.

10 The opposite end of the snapping roll |09 is provided with a coupling element in the form of a sprocket |23 (Figures 4 and 14), by means of which the snappingv roll is driven by an output element to bev subsequently described. The snapping roll 109 is supported solely by the bearing 4assembly 111-110 at its forward end and by the drive connection or coupling at its rear end. The 'forward bearing assembly provides a ilexibleor articulate connection-for the snapping roll which facilitates assembly and adjustment of the roll, all of which will appear below.

The inner sub-assembly includes a 'snapping'roll 124 which is carried at its forward end by a bearing assembly 125, the details of which are not important here. The rear end of the snapping roll |24 isi-provided with a coupling element vin the form of a sprocket |26 (Figures 4 and v15) which, like the sprocket |23 on the snapping roll |09, -forms part of a coupling for the drive connection of the snapping roll, the details of which will be described below` in connection with the description of the driving mechanism.

The inner snapping sub-assembly `|00 carries at its forward 'end a sprocket 121 which forms'part of crop-handling or crop-engaging means, here in the form of v'an endless gathering chain |28 (Figure 2).

This chain extends lengthwisejof the sub-assembly and -above 'and alongside the inner snapping roll 12 4, generally in the conventional manner. The rear portion of lthe chain is looped about a sprocket |29 which is mounted on a shaft |311 projecting upwardly from the oli'- set casing portion-Hof the casing 31 (Figures 2, 4, 5, 8 and l1) the details of which will be further described in connection with Ithe driving mechanism. y .y v

The outer sub-assembly 10| includes an outer gatheringchain |31 (Figure 2) which is looped about a pair of longitudinally spaced sprockets |32 and 13 3 and also about an idler sprocket '134. The frame member carries intermediate its front and rear ends a gear box |35 (Figure 5) within which is suitable gearing for driving an upstanding shaft '|36 (Figures 4A and 5) to the upper end of which the gathering chain sprocket |33 iskeyed.

This;k shaft -3I and has keyed;thereto.:aV secondelementigin the form of a sprocket |19 (Figure 4). This sprocket, when the husking unit is assembled to the casing 31, is coaxially alined with the coupling sprocket 81 on the forward end of the wooden husking roll 3| and the two sprockets are interconnected by a coupling chain or its equivalent as indicated at |80 in Figure 2. The front wall or plate 52 of the husking unit is provided with an aperture |80a Figure 13) through which the coupling sprocket |19 on the shaft |18 extends.

The idler shaft |58 carries thereon for rotation with the idler gear |51 a pinion |8| which is in constant mesh with a gear |82 keyed to an output shaft |83. This shaft projects outwardly through the rear wall 42 of the casing 3'1 and, when the husking unit is assembled to the casing 31, is coaxially alined with the forwardly projecting shaft 92 of the husk auger 9|. The shafts 92 and |83 lre interconnected by a coupling |84 (Figure 5). l

The gear |82l is in constant mesh with a pinion |85 keyed tc an output shaft |86. This shaft extends rearwardly and. when the husking unit is assembled to the casing 31, is coaxially alined with the shaft 95 at the forward end of Athe shelled-corn auger 94. The two shafts 95 and |86 are interconnected by a coupling |81 (Figure 5). The shafts |33 and |85 extend rearwardly through the rear wall 42 of the casing,r

31 and also extend rearwardly through the front wall or plate 62 of the husking unit, the shafts extending respectively through the openings 93 and 95 (Figure 13) provided in this plate.

Miscellaneous two-row machine is provided. Whether or not the machine is a single row or a multiple row machine is immaterial forY the present purposes.

In the tractor-mounted picker illustrated, the row units are provided with appropriate shielding or styling.

The shielding structure for the left-hand row unit comprises forward and rearward parts |88 and |88. The forward part |88 is in the form of aV gathering shield and may be of any conventional shape or construction. The rear part extends longitudinally over the rear portion of the gathering and snapping unit and substantially encloses the upper portion of the husking unit. The outer side wall of the shielding or styling |83 includes at a lower forward portion thereof an opening |98 through which access may be had to the adjusting nut 2| for the outer snapping roll |08.

The right-hand shielding structure is similarly constructed and is symmetrical rather` than identical. The gathering point for the righthand unit is visible at |9! in Figure 6. A center shield |92 is provided for enclosing the forward portion of the tractor and is disposed ahead of the steerable front truck 2| of the tractor. This center shield may be appropriately carried by and between the two row units. The arrangement is such that the center shield |90 is liftedv when the row units are lifted by the power lift v means. The range of movement of the power lift means lis suchas to elevate both row units and the center shieldingstructure '|82 to such'' height that the steerable front truck 2| may be turned in either direction through its maximum range, as will be evident from an examination of Figures 3 and 6.

The wagon elevator forms no part of the present invention and therefore will not be disclosed beyond what is illustrated. I

Summary the lubrication of the drive and insuring long life:

thereof by excluding dirt and dust. Further, enclosure of the major portion of the drive elimi-v nates hazards to the harvester operator.

The structural relationship of the two maincomponents 33 and 31 is such as to accomplish the elimination of expensive and complicated angle har constructions that have characterized pickers in the past. The flexible connection of the snapping rolls |89 and |24 respectively to the snappingroll output shafts |66 and |10 facilitates assem-4 bly and adjustment of Athe snapping rolls, since perfect axial alinement is impossible because of spreading of the rolls in operation and because of adjustmentat the lower ends o f the rolls.

yVarious other features and important objects of the invention not specifically enumerated above will undoubtedly occur to those versed in the art, as will several modifications and alterations in the preferred form of the invention illustrated, all of which may be achieved without departing from the spirit and scope of the -inven tion as defined in the appended claims.
